Ⅰ Principle of high frequency induction heating The principle of high frequency induction heating is that apply high frequency alternating current to a conduct that is curled to cyclic (normally copper tube) to produce flux, then put the metal in this area to make the flux run through it, and eddy current will be generated in the direction of self-capturing with flux (rotary current), the induced current then generates heat under the influence of the eddy current, so this heating method is called induction heating. Hence, metal and other objects under heated can be heated without contact. At this moment, the character of the eddy current relies in that the induction heating on the object nearby the coil is outwardly strong but inwardly weak. With this principle, the heating body can be concentratedly heated where needed to achieve instantly effect, thereby the production output and work capacity are both improved.

Ⅲ Main features 1. The company adopts the latest current alternating control technology to deliver higher reliability and durability. 2. Constant power control and optimized heating effect: It is featured with constant current and power control, which optimizes the heating process of metal to the maximum to realize high efficient and speed heating, therefore the superiority of products is brought into full play. 3. High efficiency and energy conservation to save your cost: All things being equal, its energy efficiency is much higher than conventional tube high frequency heating equipments for it can save twice electricity as much as that of the latter. So it seems that our products wastes its “power” on a petty job, gets twice the result with half the effort and reduces the electrical load and compatibilization to save your cost. 4. Very small volume and weight: The products are only 40-70Kg in weight, which is fraction or even several tenth of conventional equipments, so it is convenient for transportation and installation, use and maintenance, and can save lots of space for you. 5. Convenient and easy for installation and use: By connecting corresponding water, electrical and heating inductors and workpieces according to the instruction, the machine could be switched on without waiting for preheating. A simple heating adjusting knob enable you to achieve needed heating effect, and you can use this product easily without special training. 6. Safety: Compare this product adopts low voltage (several hundred volts) with conventional high frequency products employ high voltage (higher than 10000 volts), the formal can efficiently prevent electric shock and high frequency radiation to lift your worry. 7. Multi-function It is featured with heating-heat preservation two stage setting, the power of these two stages is adjusted respectively. Heating and heat preservation processes are available to adapt to lot sizing and repeatedly heating site. More than ten kinds of fault protections and displays including over current, over voltage, under 3
